That workaround works!  Thanks so much!  I'm using Anaconda to control the environment, and apparently the PyQt version there is rather out of date.  It looks like 5.9.2 is from almost 3 years ago, Wow.  Conda-forge has 5.12.3 which at least is from last year, but still too old to have the fix you mention.  I should probably at least upgrade to that version, though.  (I see that I would need to invoke QtCore.pyqt5_enable_new_onexit_scheme(True) if using 5.13.x.)

For now I've put the workaround in place with a comment indicating I want to upgrade to 5.14 or newer when I can.  I understand the workaround can't be trusted to be perfect, but so far it's immensely more successful than what I had before.  Thank you so much!  That really helps!
